Specification of'Letters Patent. Patented N 3() 1920 Application filed: .l'anuary '30, 1920. Serial;No. 355,035.

, To (4Z5 whom it may concern Be it known that l, Einizn'nn Vonsnonnn, a citizen of the United States, and a resident of Qincinnati, in the county of Hamilton and fitate of ()hio, have invented certain-new and useful Improvements in lVindow-Ventila tors, of which the following is a specification.

This invention relates to ventilator inserts for use in the space afforded by lowering an,

upper sash or raising a lower sash, or adjusting both sashes ofa window the desired distance to permit the entrance of fresh: air from without and the outlet of foul. air

from within, and its object is tolprovide a plate or body-portion having one or more orifices therein that are hooded or capped from the outside and screened so as to allow aj free circulation of air tlierethrough but without the passage of foreign material, insects, birds and the like into the chamber where,

the window is located, the screens being easily applied to andremoved from the said capped orifices and the plate or body-portion of the device being provided with stops and outwardly-turned lugs whereby it is properly held in placein the window frame and the sashes free to slide to and from closing position without hindrance and at will.

In the accompanying sheet of drawings, Figure 1 is a fragmentary perspective view showing the outer face of a window 1 with my improved telescopic, ventilator filler member or insert in attached position and with the upper sash lowered the desired distance for the ventilator; Fig. 2, an elevation of the inner face of the ventilator showing a shallow perforated metal screen .in the vent-orifices thereof; Fig. 3, a view similar to Fig. 2, but with full-size screen fillings in the vent-orificesg Fig. 4, a perspectlve View of one outer end of the device, showing the orifice protector hood or cap, the outwardly-turned lugs for the fastening-nails and the end stop lugs or extensions; Fig. 5, a vertical section taken on the line 5, 5, of Fig. 2, but with same taken-on a larger scale Fig. '6, a vertical section taken on line 6, 6, or Fig. 2; tion taken on the line 7, 7 of Fig. 3; and Fig. 8, a diagram of the strip of sheet-metal used in forming the protector hood or cap with short tongues that are adapted to enslots in the main-plate or hody-portion Fig. 7 a vertical sec-' of the device for bending over on the inner face of suchmain-plate into fastening position.

9 indicates a main-plate or body-portion 1nacle of sheet-metal and provided with an elongated orlfice or opening. 10 through which the ventilation is eflected, a screen 11 being used in the said orifice to duly filter the air passing therethrough. v

In the use of my device it is desirable to providethe same in pairs of air-inlet filler members or in'sertsthatare lapped or bent over along their top and bottom edges, as

seen at 12 and 13, for longitudinal telescopic-engagement to accommodate various widths of windows. I will describe, however, but one of the filler inserts, as the other is the same except as to the telescopic bentover upper and lower edges of the metal in thetwo members, one bent-over edge 12, on onej member, (see Figs. 5v and 7,) being a flatly -closed one, and the other bent-over edge 13 on'the other member (see Figs. 4 and 6); being anopen one,the flatly-lapped edge 12 lying within the openly-folded one 13 for the saidtelescoping or sliding engageinent, and, also, that the outer end of each filler member or insert is provided with stop-lugs la and angled fastening-lugs 15 while their inner ends 16 are straight-cut and plain, as best seen'in Figs. 2, 3 and 4.

On the outer side of each vent-orifice 10 is provided an overhanging cap orhood 17. The oppositeclosed ends 17 and the upper inwardly-extending flange-member 17 of the cap 17 provide barriers against the accidental displacement lengthwise and up wardly, respectively, of the full-size screen 11 (Fig. 7) from its mounted position in the opening 10. The cap 17 is open only at its mouth or bottom 18 and is made of the same metal as the body-portion 9 and slopes outwardly from the latter, a lip or outwardly-flared 19 being made along the lower edge of the vent-orifice 10, as best shown in Fig. 5, to support the screen 11 at its lower edge'and, also, form a suitable wind-break toavoid drafts;

Lugs 20 are cut or turned out from the flange 19, as best shown in Fig. 7, to engage the other side of the lower edge of the screen 11 to hold it in fastened place. The metal is pliable enough to bend the lugs 20 to and from fastening place, and to turn them outwardly frorn'the face of the body-portlon 9 when it is desired to place the screen, or to re place it, especially when it is desired to remove the screen for cleaningit ot' grease, dirt and other toul or toreign matter that v ordinarily collects on it and clogs it in use;

In Figs. 2 and I have shown a perforated sheet-1netal screen 11 that is a shallow one and set in an inclined position against the inner face of the cap 17,--about midheight, while in Figs. 3 and 7 Ishow a wire mesh screen 11 that is-made to-fill the'entire vent-orifice and to stand perpendicular therein.

The perforated shallow screen of Fig. 5 saves in the useof material and; wards off foreign matter the same as the full-size screen of Fig. 7 but I wishto show'herein "-t'hat-are passed through slots (not shown) i contact.

in the plate 9 and easily bent over on the inner face of the device into fastening-position, Figs. 2 and 5 both showing how the fasteningtongues are laid over into surface '/The stop-lugs 14 are extended from the outer end of each plate 9 and rest flatly against the inner fac'eof the outer run-way s t'ripof the window-frame, and the metal is so thin that it will not prevent the free {sliding of'the sa'sh to; and from-closing posi- 1 "tion Without removing theve'ntilator.

' "As I prefer to use my device in connection] with the upper window-sash,foryventt lat ion' from the top of the window, the lugs" 15 are turned outwardly at right-angles trend -the sheet-metal, adjacent the said stopstoplugs and fastening-lugs at both ends thereof instead of a telescoping pair of plates, especially for narrow windows, or

-=when but asingle vent-orifice is required in small bath-room windows or the like.

1; A ventilator device for windows cornprising an elongated.body-portion having a vent opening therein; a removable screen in saidvent opening one or more lugs projectingupwardly from the lower edge of said vent opening, an overhanging inclined cap extend ng from the outer side of said opening and registering therewith, stop-lu s projecting beyond the opposite ends of the said body-portion,andjlugs projecting outwardly at right-angles from the said opposite ends of the body-portion adjacent the said'stop-lugsand adapted to receive fasten- V ing-nails that are driven into the windowframe so thatfthesash may freely pass for opening or closingthereof.

' 2. A window-ventilator comprising alpair of telescoping plates adapted for longitudi- .nal adjustment, vent openings provided in the plates pliable detent lugs projecting upiwardly from the outwardly-flared lower edgeof'each oi the said vent openings, an

overhanging inclined cap extending outwardly from and registering with each of said vent openings screens detachablyfit ting within the said vent. openingszand either partially or who'lly filling-said vent openings, and, outwardly-extending right-angled U l'ugslalso provided at the said outer ends of theyplatesfor the reception of fastening nails that are adapted to be driven into the 'face of the outer strip O'Iffllhe' window runways and'to-permit-the sashes to freely slide 7 p "to-and from.full'closingposition.
